Answer:
-1
Step-by-step explanation:
Given: Mean= 25 minutes.
Standard deviation= 2 minutes
x= 23 minutes.
Lets find the z-score for the number of sandwiches delivered in less than 23 mins.
Formula: Z-score= 
Z-score= 
⇒ Z-score= 
∴ Z-score will be -1
Hence, -1 is the z-score for the number of sandwiches delivered in less than 23 minutes.
The first thing you should do when dealing with implicit derivatives is to respect the rules of derivation of both the logarithm and the exponential
Then, you must regroup the terms correctly until you get dy / dx
The answer for this case is D
I attach the solution
2x + 8.....factor = 2(x + 4)
Answer:
7
Step-by-step explanation:
if h(x)=4 .. that would mean to plug 4 in as x
therefore .. 3(4)-5
3×4=12
12-5=7
Answer:
A c = -4 2/3
Step-by-step explanation:
5c +4 = 2(c-5)
Distribute
5c+4 = 2c - 10
Subtract 2c from each side
5c-2c+4 = 2x-2x-10
3c+4 = -10
Subtract 4 from each side
3c+4-4=-10-4
3c = -14
Divide each side by 3
3c/3 = -14/3
c = -14/3
Changing to a mixed numbers
c = -4 2/3
